CMYK is next in the list and though the drop-down lists several options, the default is most accu- rate. Grayscale is next, and though several choices exist, the default usually yields the best results. Primary color mode is self- explanatory, either CMYK or RGB. e default color palette changes to reflect whichever mode is chosen. Fig. 2 shows the drop-down menu of the four rendering intents available. Since this is a fairly important setting, I will briefly describe each of them. • Relative Colorimetric, the default, is suitable for logos or graphics that contain only a few out-of-gamut colors. It matches Default color management settings in CorelDRAW. (All images courtesy Doug Zender) 1 out-of-gamut colors with the closest in- gamut colors at the destination. This causes the white point to shift, so if you print on white paper, the whiteness of the paper is used to reproduce the white areas of the document. It is a good option for printed documents. • Absolute Colorimetric is suitable for logos or graphics that require more precise colors. If no match is found for the source colors, the closest match is used. This intent preserves the white point through the conversion and does not adjust for the whiteness of the paper and is best used mainly for proofing. • Perceptual is suitable for photographs and images that contain many out-of- gamut colors. e overall color appear- ance is preserved by changing all the col- ors to fit within the range of colors at the destination. It maintains the relationships between colors to produce the best results. • Saturation produces more concen- trated solid colors in graphics such as charts and graphs. Colors may be less accurate than other rendering intents. e " I have found that the perceptual rendering intent is generally the best choice for the most visually realistic rendering, as it more closely maintains the relationship of colors."
